About the job
Project Goal
The goal of this project is to create a functional, ergonomic handheld enclosure that blends:
The overall shape language and hand feel of a GBA-style device
A larger, more comfortable body to support a 5”+ screen
A modern control layout and grip ergonomics inspired by larger handhelds like the Powkiddy RGB10 Max series
The final enclosure should feel:
Comfortable during long play sessions
Balanced in the hands
Purpose-built rather than a modified off-the-shelf shell
Success = a print-ready enclosure that I can build custom electronics into.
Scope of Work
1. Enclosure CAD
Full handheld enclosure design
Split shell (front / back)
Hidden screws
Conservative, prototype-safe snap fits (optional, justified)
Designed specifically for 3D printing, not injection molding
2. Internal Layout (Mechanical only)
Mechanical placement volumes for:
5.0–5.5” display (generic envelope, not SKU-specific)
Battery
Speakers
PCB volume (RK3566 SOM + carrier assumed)
Includes:
Standoffs, ribs, bosses
Structural supports
Clearance for assembly and iteration
⚠️ No PCB routing, no electronics calculations, no EE responsibility
3. Button Mechanics
Button caps and posts
Button travel and tolerances
Suitable for tact switches or membranes
Dual analog sticks
Asymmetrical layout (Switch / Xbox style)
D-pad priority, analog sticks secondary
4. Ergonomics
Comfortable grip for extended use

4. Ergonomics
Comfortable grip for extended use
No sharp edges or pressure points
Balanced hand feel
Comfort prioritised over compactness
5. Assembly Philosophy
Prioritise easy assembly and disassembly
Designed for repeated prototype iterations
Avoid fragile features that fail after multiple builds
Manufacturing Assumptions
3D printing only (SLS / MJF preferred, SLA acceptable)
No injection molding
CAD must be print-ready
Tested tolerances for SLS / MJF
Near-production geometry without mold constraints
Deliverables
Complete enclosure CAD
Internal mechanical layout
Button geometry and mechanisms
STEP file (required)
Fusion 360 file preferred
Design ready to send directly to a 3D printing service
Collaboration & Process
High involvement, frequent feedback
Iterative development
No rush – quality first
NDA required
I retain ownership of all CAD and design files
Ideal Experience
You are a good fit if you have experience with:
Consumer electronics enclosures
Handheld or ergonomic product design
3D printing–ready CAD (SLS / MJF)
Designing for assembly and iteration
Please include examples of past enclosure or product CAD work in your proposal.
Nice to Have (Not Required)
Experience designing handheld devices
Familiarity with RK3566-class products
DFM experience for non-molded prototypes
Screening Questions (please answer)
What CAD tools do you use?
Have you designed enclosures specifically for SLS or MJF printing before?
Can you share an example of a consumer electronics enclosure you’ve designed?
How do you approach ergonomic design for handheld products?
Are you comfortable delivering print-ready CAD with validated tolerances?
If this sounds aligned, I’d love to talk.
